AI Stack Stability Checker

Most people run several AI subscriptions at once, and the real risk to that stack is rarely one tool going down — it’s a vendor quietly cutting a limit, retiring a model, or moving to metered billing between renewals. This checker turns that exposure into a single grade. Pick the tools you actually pay for and it blends each one’s constraint-stability score into a stack-level reading, then flags the weakest link — the vendor whose sourced history says it is most likely to tighten the rules on you next.

Each grade is built only from dated, sourced changes to that tool’s limits, pricing, model access and transparency, weighted toward recent moves. A high grade means few recent restrictions on record — not that the tool is better at its job. Read it as a risk signal for budgeting and dependence, not a capability ranking, and click through to any tool for the events behind its score.
